Description
The AK1573 is an integer N type frequency synthesizer with a built-in VCO (Voltage Controlled Oscillator). It consists of an eight-stage current-adjustable charge pump, reference divider, programmable divider, dual modulus prescaler (P / P + 1), and low phase noise VCO. The AK1573 realizes a complete Phase Locked Loop when combined with an external loop filter. The AK1573 features low current consumption and low noise, and because of its small package, it can be expected to reduce the size of equipment.
Key Features
Low current consumption. / Low noise.
Applications
Public safety and Community. / Emergency Wireless System. Wireless applications. Cellular BTS.
